Ukusetshenziswa kwe-resin ye-pvc yokunamathisela.
Kulinganiselwa ukuthi ngo-2000, ukusetshenziswa okuphelele kwemakethe yomhlaba wonke ye-PVC paste resin kwakungaba yizigidi eziyi-1.66 zamathani. EShayina, i-PVC paste resin inalezi zicelo ezilandelayo: Imboni yesikhumba sokwenziwa: imakethe iyonke ibhalansi yokuhlinzekwa kanye nesidingo. Kodwa-ke, uma ithinteka yintuthuko yesikhumba se-PU, isidingo sesikhumba sokwenziwa eWenzhou nakwezinye izindawo ezinkulu zokusetshenziswa kwe-paste resin singaphansi kwemikhawulo ethile. Umncintiswano phakathi kwesikhumba se-PU nesikhumba sokwenziwa unamandla kakhulu. Imboni yesikhumba saphansi: Uma ithinteka yisidingo esinciphayo sesikhumba saphansi, isidingo se-paste resin kule mboni besilokhu sincipha unyaka nonyaka eminyakeni yamuva. Imboni yezinto ezisetshenziswa ngamagilavu: isidingo sikhulu kakhulu, ikakhulukazi singeniswa kwamanye amazwe, esingesokucutshungulwa kwempahla enikeziwe... -
Isitshalo se-polyethylene esigcwele amathani angu-800,000 saqalwa ngempumelelo ngokudla okukodwa!
Isitshalo se-polyethylene esigcwele amandla esingamathani angu-800,000 ngonyaka se-Guangdong Petrochemical siyisitshalo sokuqala se-polyethylene esigcwele amandla esinohlelo oluphindwe kabili "lwekhanda elilodwa nemisila emibili", futhi futhi siyisitshalo sesibili se-polyethylene esigcwele amandla esinekhono elikhulu lokukhiqiza eShayina. Le divayisi isebenzisa inqubo ye-UNIPOL kanye nenqubo yombhede wegesi wesigaba esisodwa. Isebenzisa i-ethylene njengezinto ezisetshenziswayo eziyinhloko futhi ingakhiqiza izinhlobo ezingu-15 zezinto ze-polyethylene ze-LLDPE ne-HDPE. Phakathi kwazo, izinhlayiya ze-resin ze-polyethylene esigcwele amandla zenziwe nge-polyethylene powder exutshwe nezinhlobo ezahlukene zezithasiselo, ezishiswa ekushiseni okuphezulu ukuze zifinyelele esimweni esincibilikisiwe, futhi ngaphansi kwesenzo se-extruder enama-screw amabili kanye nephampu yegiya elincibilikisiwe, zidlula kuthempulethi futhi... -
UChemdo uhlela ukuhlanganyela emibukisweni kulo nyaka.
I-Chemdo ihlela ukuhlanganyela emibukisweni yasekhaya neyakwamanye amazwe kulo nyaka. NgoFebhuwari 16, abaphathi bemikhiqizo ababili bamenywa ukuba babe khona enkambweni ehlelwe yi-Made in China. Isihloko sale khosi siyindlela entsha yokuhlanganisa ukukhushulwa okungaxhunyiwe ku-inthanethi kanye nokukhushulwa ku-inthanethi kwamabhizinisi okuhweba kwamanye amazwe. Okuqukethwe kwekhosi kuhilela umsebenzi wokulungiselela ngaphambi kombukiso, amaphuzu abalulekile okuxoxisana ngesikhathi sombukiso kanye nokulandelela kwamakhasimende ngemva kombukiso. Sithemba ukuthi abaphathi ababili bazothola okuningi futhi bakhuthaze inqubekela phambili ebushelelezi yomsebenzi wokulandelela wombukiso. -
Isingeniso mayelana ne-Zhongtai PVC Resin.
Manje ake ngethule okwengeziwe ngomkhiqizo we-PVC omkhulu kunayo yonke eShayina: iZhongtai. Igama layo eligcwele lithi: iXinjiang Zhongtai Chemical Co., Ltd, etholakala eSifundazweni saseXinjiang entshonalanga yeShayina. Ibanga elingamahora ama-4 ngendiza ukusuka eShanghai. IXinjiang futhi iyisifundazwe esikhulu kunazo zonke eShayina ngokwendawo. Le ndawo igcwele imithombo yemvelo efana nosawoti, amalahle, uwoyela, kanye negesi. IZhongtai Chemical yasungulwa ngo-2001, yaya emakethe yamasheya ngo-2006. Manje inabasebenzi abacishe babe yi-22 000 kanye nezinkampani ezingaphansi kuka-43. Njengoba ithuthukiswe ngesivinini esikhulu iminyaka engaphezu kwengu-20, lo mkhiqizi omkhulu usungule uchungechunge lwemikhiqizo elandelayo: i-pvc resin enamandla angamathani ayizigidi ezimbili, i-caustic soda engamathani ayizigidi eziyi-1.5, i-viscose engamathani ayizigidi ezingu-700,000, i-calcium carbide engamathani ayizigidi ezingu-2.8. Uma ufuna ukuqoqa... -
Ungakugwema kanjani ukukhohliswa lapho uthenga imikhiqizo yaseShayina ikakhulukazi imikhiqizo ye-PVC.
Kufanele sivume ukuthi ibhizinisi lamazwe ngamazwe ligcwele izingozi, ligcwele izinselele eziningi kakhulu lapho umthengi ekhetha umhlinzeki wakhe. Siyavuma futhi ukuthi amacala okukhwabanisa ayenzeka yonke indawo kuhlanganise naseShayina. Bengingumthengisi wamazwe ngamazwe cishe iminyaka eyi-13, ngihlangabezana nezikhalazo eziningi ezivela kumakhasimende ahlukahlukene akhohliswe kanye noma izikhathi eziningana ngumhlinzeki waseShayina, izindlela zokukhohlisa "zihlekisa" kakhulu, njengokuthola imali ngaphandle kokuthunyelwa, noma ukuletha umkhiqizo osezingeni eliphansi noma ngisho nokuletha umkhiqizo ohlukile kakhulu. Njengomhlinzeki nami, ngiyaqonda ngokuphelele ukuthi umuzwa unjani uma umuntu elahlekelwe yinkokhelo enkulu ikakhulukazi lapho ibhizinisi lakhe lisanda kuqala noma engusomabhizinisi oluhlaza, okulahlekile kumele kube yinto emangalisayo kuye, futhi kufanele sivume ukuthi ukuze sithole... -
Ukusetshenziswa kwe-caustic soda kuhilela imikhakha eminingi.
I-Caustic soda ingahlukaniswa ibe yi-flake soda, i-granular soda kanye ne-solid soda ngokwesimo sayo. Ukusetshenziswa kwe-caustic soda kuhilela amasimu amaningi, okulandelayo yisingeniso esiningiliziwe kuwe: 1. I-petroleum ehlungiwe. Ngemva kokugezwa nge-sulfuric acid, imikhiqizo ye-petroleum isenazo ezinye izinto ezine-acidic, okumele zigezwe ngesisombululo se-sodium hydroxide bese zigezwa ngamanzi ukuze kutholakale imikhiqizo ehlungiwe. 2. ukuphrinta nokudaya Kusetshenziswa kakhulu kumadayi e-indigo kanye namadayi e-quinone. Enqubweni yokudaya amadayi e-vat, isisombululo se-caustic soda kanye ne-sodium hydrosulfite kufanele kusetshenziswe ukuze kuncishiswe kube yi-leuco acid, bese ku-oxidized ibe sesimweni sokuqala sokungancibiliki ngama-oxidants ngemva kokudaya. Ngemva kokuba indwangu yekotini iphathwe ngesisombululo se-caustic soda, i-wax, i-grease, i-starch nezinye izinto ... -
Ukubuyiselwa kwesidingo se-PVC emhlabeni wonke kuncike eShayina.
Njengoba singena ngo-2023, ngenxa yesidingo esicothayo ezifundeni ezahlukene, imakethe yomhlaba wonke ye-polyvinyl chloride (PVC) isabhekene nokungaqiniseki. Phakathi nengxenye enkulu ka-2022, amanani e-PVC e-Asia nase-United States abonise ukwehla okukhulu futhi ehla ngaphambi kokungena ngo-2023. Njengoba singena ngo-2023, phakathi kwezifunda ezahlukene, ngemuva kokuba i-China ilungise izinqubomgomo zayo zokuvimbela nokulawula ubhubhane, imakethe ilindele ukuphendula; i-United States ingakhuphula amazinga enzalo ukuze ilwe nokwehla kwamandla emali futhi inciphise isidingo se-PVC sasekhaya e-United States. I-Asia, eholwa yi-China, kanye ne-United States bandise ukuthunyelwa kwe-PVC phakathi kwesidingo esibuthakathaka somhlaba wonke. Ngokuphathelene ne-Europe, lesi sifunda sisazobhekana nenkinga yamanani aphezulu amandla kanye nokwehla kwamandla emali, futhi cishe ngeke kube nokululama okuqhubekayo emalini yenzuzo yemboni. ... -
Uyini umthelela wokuzamazama komhlaba okunamandla eTurkey ku-polyethylene?
ITurkey iyizwe elihamba phakathi kwe-Asia neYurophu. Icebile ngemithombo yamaminerali, igolide, amalahle kanye neminye imithombo, kodwa ayinayo imithombo kawoyela negesi yemvelo. Ngo-18:24 ngoFebhuwari 6, ngesikhathi saseBeijing (13:24 ngoFebhuwari 6, isikhathi sendawo), ukuzamazama komhlaba okungu-7.8 ngobukhulu kwenzeka eTurkey, okujule ngamakhilomitha angama-20 kanye ne-epicenter engama-degrees angu-38.00 enyakatho ye-latitude kanye nama-degrees angu-37.15 empumalanga ye-longitude. I-epicenter yayiseningizimu yeTurkey, eduze komngcele weSiriya. Amachweba amakhulu e-epicenter kanye nendawo ezungezile kwakuyiCeyhan (Ceyhan), Isdemir (Isdemir), kanye neYumurtalik (Yumurtalik). ITurkey neChina zinobudlelwano bokuhweba ngepulasitiki obuhlala isikhathi eside. Ukungeniswa kwe-polyethylene yaseTurkey ezweni lami kuncane kakhulu futhi kwehla unyaka nonyaka, kodwa inani lokuthumela kwamanye amazwe liyancipha kancane kancane... -
Ukuhlaziywa kwemakethe yokuthumela ngaphandle i-caustic soda yaseShayina ngo-2022.
Ngo-2022, imakethe yokuthumela ngaphandle ye-caustic soda yezwe lami iyonke izobonisa ukuthambekela okushintshashintshayo, futhi isiphakamiso sokuthumela ngaphandle sizofinyelela ezingeni eliphezulu ngoMeyi, cishe amadola aseMelika angu-750/ton, kanti isilinganiso sokuthumela ngaphandle sanyanga zonke sizoba amathani angu-210,000. Ukwanda okukhulu kwenani lokuthumela ngaphandle kwe-caustic soda ewuketshezi kungenxa yokwanda kwesidingo emazweni afana ne-Australia ne-Indonesia, ikakhulukazi ukuqaliswa kwephrojekthi ye-alumina engezansi e-Indonesia kukhulise isidingo sokuthengwa kwe-caustic soda; ngaphezu kwalokho, ethintekile ngamanani amandla aphesheya kwezilwandle, izitshalo ze-chlor-alkali zasendaweni eYurophu seziqalile ukwakhiwa. Akwanele, ukuhlinzekwa kwe-caustic soda ewuketshezi kuncishisiwe, ngaleyo ndlela ukwandisa ukungeniswa kwe-caustic soda nakho kuzokwakha ukwesekwa okuhle... -
